The not shown pull head that goes out is slided; Make two engages head 33b, when 33c is engaged with each other; For simultaneously colliding, the front bulkhead 36b of the engagement projections 34c that prevents to mesh gradually and the engages head 33b that meshed contacts; The one side engagement, and on the front bulkhead 36b of engages head 33b, form oblique shape face 37b.Equally, in engages head 33a, 33c, in order to prevent to contact with the collision of the other side's who meshes engagement projections, and respectively at the oblique shape face of the last formation of front bulkhead 36a, the 36c of engages head 33a, 33c 37a, 37c.
In addition, in Fig. 5, expression is formed on the zone of engagement projections 34b through the oblique shape face 37a on the front bulkhead 36a that is formed on engages head 33a on the engages head 33b, is inserted into the state in the engagement recess 35a.
Then, as shown in Figure 6, through on the front bulkhead 36 of engages head 33, forming oblique shape face 37, the resistance to sliding of pull head can be carried out the slip of pull head swimmingly in the time of can reducing engagement.Then, be used for bi-directional zip, the sliding of the pull head in the time of can improving the monolateral engaging tooth of the metal system of making and be engaged with each other through the monolateral engaging tooth of metal system that will constitute by the device of patent documentation 1.
But; Even the monolateral engaging tooth of metal system being made up of the device of patent documentation 1 is used under the situation of bi-directional zip; When horizontal pulling force was applied to bi-directional zip after engagement, horizontal tension was in the opening edge 39 of the engagement recess 35 of the monolateral engaging tooth of metal system shown in Figure 6.And, because tiltedly shape face 37c is formed on the front bulkhead 36 of engages head 33, so the wall thickness of the opening edge 39 of engagement recess 35 is configured thin.
Therefore, in the opening edge 39 of the engagement recess 35 of wall thickness attenuation, then the deflection of opening edge 39 increases as if the moment loading that produces because of horizontal pulling force.So,, then produce the bad danger of sliding of pull head if opening edge 39 deflections get greatly.
Therefore, being improved at the moment loading that produces because of horizontal pulling force during in the opening edge 39 of engagement recess 35, making the little monolateral engaging tooth of metal system of deflection of opening edge 39, is the monolateral engaging tooth of metal system of patent documentation 2 records.In the monolateral engaging tooth of the metal system of patent documentation 2, as shown in Figure 6, form rib 38 at the medial surface of the front bulkhead 36 of engages head 33.

Other topmost being characterised in that of bi-directional zip of the present invention possesses the zip strip that the monolateral engaging tooth of the metal system of the invention described above is formed with being spaced on the side edge part in opposite directions that is arranged on the pair of right and left zipper strip of regulation and constitutes.
The invention effect
In the monolateral engaging tooth of relevant metal system of the present invention, in engagement recess, form the upper angled face that has a down dip.Therefore, can describe through being formed on the upper angled face side on the engagement recess, be inserted into the track in the engagement recess with the engagement projections of the other side's side that meshes in the engagement recess.Then, as the engages head of the other side's side, through the upper angled face side of engagement recess of engagement, in view of the above, can and the engagement projections of engagement next time between, the gap of avoiding colliding contact is set.Therefore, engagement projections can be gradually swimmingly with the engagement recess engagement of the other side's side of engagement.
In the monolateral engaging tooth of metal system of patent documentation 1,2 records; As shown in Figure 5; The engagement projections 34b of engages head 33b simultaneously describes through being formed on the oblique shape face 37a side on the engages head 33a; Be embedded into the interior track of engagement recess 35a of engages head 33a, one side meshes with engagement recess 35a.In addition, same, the engagement projections 34c of engages head 33c simultaneously describes through being formed on the oblique shape face 37b side on the engages head 33b, is embedded into the interior track of engagement recess 35b of engages head 33b, and one side meshes with engagement recess 35b.
Like this, in the monolateral engaging tooth of metal system of patent documentation 1,2 record, through oblique shape face side, in view of the above, with the engagement projections of engagement next time between be provided with and avoid colliding the gap that contacts.Relative therewith; In the monolateral engaging tooth of relevant metal system of the present invention; Engagement projections is through the upper angled face side on the engagement recess that is formed on the engagement target; In view of the above, can simultaneously avoid engagement projections to contact with the collision of the engagement recess of engagement target, one side is avoided contacting with the collision of the engagement projections of the engages head of engagement next time.
In addition; The monolateral engaging tooth of metal system of the present invention is being used under the situation of bi-directional zip; When horizontal pulling force was applied to bi-directional zip after engagement, the moment loading that produces because of the pushing force from the engagement projections of the other side's side that is meshing was in the opening edge of engagement recess.That is the moment that, produces because of horizontal pulling force acts on inner peripheral surface and the connecting portion of upper angled face of engagement recess of front-end edge side of the engages head of the monolateral engaging tooth of metal system greatly.
But, thick because the wall thickness of the opening edge of engagement recess is configured in the present invention, so, even the moment loading that produces because of horizontal pulling force in the opening edge of engagement recess, the deflection of the opening edge of engagement recess is also minimum.Like this, the abominable such distortion of sliding of pull head can not produced in the front-end edge side of engages head, can keep the sliding of pull head well.
In addition; In the present invention, because the upper angled face is formed between the opening edge of front-end edge and engagement recess of engages head, so; The collision contact area of engagement projections and engages head that can constitute the other side's side that engagement comes is few, can significantly improve the sliding of pull head.
Have again, in the present invention, because make the structure that sets discretely between the ora terminalis of upper angled face of front-end edge and this front-end edge side of engages head, so the wall thickness that can constitute the opening edge that makes engagement recess is thicker.Therefore, though the moment loading that produces because of horizontal pulling force in the opening edge of engagement recess, the deflection of the opening edge of engagement recess is also littler.
In the present invention, because form lower beveled through the inner peripheral surface in engagement recess, the engagement projections that will mesh the other side who comes easily is housed in the engagement recess, and, the next the other side's of engagement engagement projections is thrown off from engagement recess.
In addition, constitute more shallowly than the angle of inclination of lower beveled through the angle of inclination with the upper angled face, the butt area of lower beveled that can constitute the engagement projections that meshed and engagement recess is wide, can constitute the engagement grow when making engagement.
Like this because can the wall thickness of the opening edge of engagement recess be configured thick, so, can further improve the rigidity of the opening edge of engagement recess.In addition, can increase the butt area of lower beveled of engagement projections and the engagement recess of the other side's side that is meshing.
That is, can make the engagement projections that is meshing compare the bottom surface side that is positioned at the engagement recess that meshes target with the opening edge of lower beveled with the position of centre of gravity of the engagement projections of the face side of the lower beveled butt of engagement target.In other words, engagement projections can compared with the opening edge of lower beveled under the low state of waist, with the engagement recess engagement of engagement target.
Therefore; Even because horizontal pulling force; With the opening edge of engagement recess is the engagement projections that the turning moment at center acts on the other side's side that is meshing; The engagement projections of the other side's side that also can prevent to mesh is the situation that rotate at the center with the opening edge of the engagement recess of engagement target, can prevent that engagement separately.
In the present invention, preferably, big than 0 degree as the angle of inclination of upper angled face, below 7 degree.More suitably be to make and hope to be the structure below above 7 degree of 3 degree.Through constituting the angle of inclination of upper angled face at such angular range, can the butt area of the lower beveled of engagement projections that has meshed and engagement recess be constituted as keeping as the area of the joggled strength of slide fastener.
If the angle of inclination of upper angled face is constituted than the big angle of 7 degree, the engagement projections that has then meshed and the butt area of the lower beveled of the engagement recess of engagement target narrow down, and weaken with respect to the joggled strength of horizontal pulling force.And; In this case; In the engagement projections that is meshing, be positioned near the opening edge of lower beveled of engagement recess of engagement target with the position of centre of gravity of engagement projections of the face side of the lower beveled butt of engagement target, or compare with the opening edge of lower beveled and to be positioned at the top.
That is, engagement projections is under the high state of waist at the opening edge with respect to lower beveled, with the engagement recess engagement of engagement target.
If like this, the engagement projections that is meshing is under the state of high waist, and with the engagement recess engagement of engagement target, then when horizontal pulling force played a role, engagement was separated easily.
In the monolateral engaging tooth of metal system of the present invention; Under the horizontal width dimensions with the left and right directions of upper angled face constitutes than 92% of the horizontal width dimensions of the left and right directions of the bottom surface of engagement recess long situation; The horizontal width of upper angled face is configured wide, and the wall thickness of the upper side of the front bulkhead of engages head is configured few.In view of the above, produce the undercapacity of engagement recess, and, with respect to the intensity reduction of horizontal pulling force.
In addition; Under the horizontal width dimensions with the left and right directions of upper angled face constitutes than 89% of the horizontal width dimensions of the left and right directions of the bottom surface of engagement recess short situation; The horizontal width of upper angled face is configured narrow; The position of the both side ends side of the upper angled face of the engages head area that collision contacts with engagement projections increases, and the sliding of pull head worsens.
Therefore; The horizontal width dimensions of the left and right directions of upper angled face is constituted 89%～92% size range at the horizontal width dimensions of the left and right directions of the bottom surface of engagement recess; Owing to guarantee the sliding of pull head well; Guaranteed the intensity of the front bulkhead of engages head, so, be the structure of hoping.
Use the relevant monolateral engaging tooth of metal system of the present invention, can make bi-directional zip.Through constituting by this way, can significantly improve the sliding of two pull heads, and, can constitute the bi-directional zip that engagement can not removed because of horizontal pulling force.

Embodiment
Fig. 1 is the stereogram of the monolateral engaging tooth of metal system of relevant this embodiment.In addition, Fig. 2 (a) is the vertical view of engages head, and Fig. 2 (b) is the II-II cutaway view of Fig. 2 (a).Fig. 2 (c) is the III-III cutaway view of Fig. 2 (a).Fig. 3 has represented to use the vertical view of bi-directional zip of the monolateral engaging tooth of metal system of relevant this embodiment, and Fig. 4 representes the engagement situation of the monolateral engaging tooth of metal system as the major part cutaway view.
In addition; In the present invention; The fore-and-aft direction of the monolateral engaging tooth of metal system is meant the direction that becomes the bandwidth direction when being installed in the monolateral engaging tooth of this metal system on the zipper strip; In addition, the left and right directions of the monolateral engaging tooth of metal system and above-below direction are meant the direction that becomes direction in the band table and strip length direction when monolateral engaging tooth is respectively installed on the zipper strip with this metal system respectively.
The monolateral engaging tooth 1 of the metal system of relevant embodiment shown in Figure 1 can cut off by the gauge of stipulating through the metal system wire rod that will be called as the Y bar, with respect to the engages head 3 of the engaging tooth after cutting off, carries out punch process from above-below direction, comes continuous the manufacturing.Perhaps; Metallic plate is carried out at least once above punch process; Metallic plate to carrying out punch process is bored a hole according to the peripheral shape of the monolateral engaging tooth 1 of metal system, in view of the above, can make the monolateral engaging tooth 1 of metal system of relevant embodiment shown in Figure 1 continuously.
Through above-mentioned punch process, can on a side's of the above-below direction of engages head 3 face, form engagement projections 4, on the opposing party's face, form engagement recess 5 and upper angled face 8.Then, of the back, in the inner peripheral surface 10 of engagement recess 5, become the simple shape that is connected with upper angled face 8 as the lower beveled 10a of the face of the front-end edge side of engages head 3.According to this structure,, also can form engagement recess 5 and upper angled face 8 through at least punch process even do not prepare the metal pattern of a plurality of punch process.
Like Fig. 1, shown in Figure 2; Rear side at the monolateral engaging tooth 1 of metal system; Form pair of right and left foot 2, on the engages head 3 of the front side of the monolateral engaging tooth 1 of metal system, form engagement projections 4 (referring to Fig. 2 (b) in the one side side of the above-below direction of the monolateral engaging tooth 1 of metal system; Fig. 2 (c)), form engagement recess 5 in the another side side.
In the front-end edge 7 lateral engagement recesses 5 of the front side of the engages head 3 of the above-mentioned another side side of the monolateral engaging tooth 1 of metal system, form the upper angled faces 8 that have a down dip.As upper angled face 8, also can as above-mentioned, form through punch process, still, owing to do not carry out punch process, but, can be formed on front-end edge 7 sides of engages head 3 through cut, grinding.But, under the situation that has formed upper angled face 8 through punch process, because therefore the plastic deformation during shaping upper angled face 8 grades and can produce work hardening, can improve the rigidity of upper angled face 8 grades.
The inner peripheral surface 10 of engagement recess 5 is the shape of the mortar shape shown in Fig. 2 (a)～Fig. 2 (c), is constituted as the shape that expands out laterally from the bottom surface 5b of engagement recess 5.Then, in the inner peripheral surface 10 of engagement recess 5, the lower beveled 10a of front-end edge 7 sides of engages head 3 is the structures that are connected at the opening edge 5a of engagement recess 5 with upper angled face 8.
Shown in Fig. 2 (b),, can be than the big angle below 7 degree of 0 degree as the tilt angle alpha of upper angled face 8.Preferably make the angle of tilt angle alpha below 7 degree more than 3 degree of upper angled face 8, this is better structure.In addition because the tilt angle alpha of upper angled face 8 is configured more shallow than the inclination angle beta of lower beveled 10a, so as the inclination angle beta of lower beveled 10a, constituting as the angle below above 30 degree of 20 degree is the structure of hoping.
Then; Being formed in 20 through the inclination angle beta with lower beveled 10a spends to the angular range of 30 degree; In horizontal tension during in the bi-directional zip 1 that is meshing shown in Figure 3; The part that can make horizontal pulling force at lower beveled 10a to above discharge, and can accept by lower beveled 10a and discharge the remaining horizontal pulling force in back.
In addition, shown in Fig. 2 (c), can the size of the horizontal width B of upper angled face 8 be constituted 89%～92% the size of size of horizontal width A of the bottom surface 5b of engagement recess 5.Constitute under the situation than 92% of the size of the horizontal width B of upper angled face 8 long size in the size with the horizontal width A of bottom surface 5b, the horizontal width B of upper angled face 8 is configured wide.Therefore, the wall thickness of the upper side of the front bulkhead 6 of engages head 3 reduces, and produces the undercapacity of engagement recess 5, and reduces with respect to the intensity of horizontal pulling force.
In addition, constitute under the situation than 89% of the size of the horizontal width B of upper angled face 8 short size in the size with the horizontal width A of bottom surface 5b, the horizontal width B of upper angled face 8 is configured narrow.Therefore, the position of the both side ends side of the upper angled face 8 of engages head 3 area that 4 collisions contact with engagement projections increases, and the sliding of pull head is abominable.
Through constituting by this way, during in bi-directional zip 1 shown in Figure 3, can increase the butt area of the engagement projections 4 and the engagement recess 5 of the other side's side that is meshing with engagement recess 5 in horizontal tension.According to this structure, can prevent that when horizontal pulling force plays a role the engagement projections 4 of the other side's side is from leaving with the engagement of engagement recess 5, and can accept horizontal pulling force by the engagement projections 4 of the other side's side and the butt area of engagement recess 5.
Then, be configured widely through butt area, can reduce with respect to the pulling stress of each unit are of horizontal pulling force with engagement projections of the other side's side 4 and engagement recess 5.In addition, can the wall thickness of the front bulkhead 6 of the opening edge 5a of engagement recess 5 be configured thickly, can improve the rigidity of the opening edge 5a of engagement recess 5.
Have again; Even in horizontal tension; With the opening edge 5a of engagement recess 5 be the turning moment at center act on engagement recess 5 under the situation of engagement projections 4 of the other side's side of meshing, also can increase the butt area of lower beveled 10a of engagement projections 4 and the engagement recess 5 of the other side's side that is meshing.In view of the above, the engagement projections 4 of the other side's side that can prevent to mesh is that the direction that middle mind-set is separated is rotated with the opening edge 10a of engagement recess 5, can prevent that engagement separately.
